Richie is quite scary, when he first met Russell, he scared him. Like when he said "This never over okay? Every time you turn around,
every time you think the coast is clear, you better be watching for me." That scared Russell a lot. Like everyone know he is a bully, well he scared Russell,
he punched him, what else can he be.

In the end, Richie becomes nicer to Russell, it is like they are now friends.
